Position Size Calculator

What is position sizing?

Position sizing determines how many contracts you trade on a given setup. It is the bridge between your risk budget and your stop placement. Get it wrong and a single loss can wipe out a week of gains. Get it right and you survive the drawdowns that knock other traders out.

Why it matters for futures traders

Futures contracts are leveraged instruments. One ES contract moves $50 per point. A 4-point stop on 2 contracts is $400 at risk. Most traders set their stop, then pick a round number of contracts without doing the math. That is how a "small position" turns into a $600 loss on what was supposed to be a $300 risk day.

Consistent position sizing also removes emotion from the equation. When every trade risks the same dollar amount, you stop oversizing on conviction plays and undersizing when you are scared. The math decides. You follow.

How to use this calculator

Select your instrument (ES, MES, NQ, MNQ, or add a custom instrument with its point value and tick size). Use the preset risk levels as quick buttons, or type any dollar amount into the risk input. Set your stop distance in points. The calculator shows how many whole contracts fit inside your risk budget, rounding down to avoid over-risking.
